Was for 2000 jeep cherokee. After oil change old unit was reflecting high oil pressure. Apparently common problem. New pressure switch and all was good again.

I would advise anyone to stay away from this product. Normally, I have had good results with BWD and/or Carquest parts, but this oil pressure switch is an exception. The switch installs easily and works initially, but that is as far as it goes.

The first two worked for about 2 months (maybe 3,000 miles). Suddenly, the oil pressure went from the usual 40 PSI to about 12 and wouldn't go higher at any RPM. I just about panicked the first time since I had just changed the oil and thought maybe the oil pressure was somehow being affected by that.

I had a mechanic check the pressure (which was fine) and put another BWD switch in. Reading was fine again. This one worked for another 2 months then the same thing happened.

I put another BWD switch in and it worked for about an hour before again going to 12 PSI. I took a slow approach to diagnosis repeating each step short of replacement (even removing the adapter that the switch screws into to see if there was debris). Nothing short of replacement fixed anything.

Today, I just put in another BWD switch... pressure reads good.... let's see how long this 4th switch works.

The switch has a lifetime replacement guarantee which Advance Auto has honored, but I really don't want to spend a lifetime replacing something which usually lasts for many, many years.

Best advice... buy one not made by BWD (check first, because this is the manufacturer for most retailers).

              My 2000 Grand Cherokee's oil pressure guage dropped to zero at idle. It didn't show signs of stalling so I figured it was the oil pressure switch. Bought this one at a reasonible price and it fixed the problem. Easy to replace old and install new. Highly recommend.

              The oil pressure would drop giving an error. Replaced the sensor and have not had the error come back. You have to remove the oil filter to replace the sensor.

                I was ready to scrap my Jeep 4.0 L with 216k miles, however, the low oil pressure indication on my dash oil gauge was fully rectified by installing a replacement oil pressure sender.

                    Hi Rich, I'm glad to assist you. The oil pressure switch and the oil pressure sending unit are same. The oil pressure sending unit controls the oil pressure light or gauge depending on what a car is equipped with. Both the BWD Part No. S4191 and the Omix-Ada Part No. 17219.12 oil pressure sending units are exact fit for your 2000 jeep Cherokee 4.0l.

                  Is this oil sending unit specifically for Jeeps that have a oil light and not a oil gauge? Or is this unit used for both styles on a 2002 Jeep Liberty Limited 3.7 liter.

                    A:

                    If your oil pressure is remaining that high, I would suggest having it checked with a manual pressure gauge to see if the reading is accurate. It sounds to me as if you might have a bad oil sending unit. If the oil pressure sending unit is good, check the oil pressure relief valve. It may be stuck closed resulting in high pressure reading.

                    This could be the cause of your issues, but unfortunately we are unable to diagnose what is wrong with your vehicle without being able to be there with your vehicle. We highly recommend taking your vehicle to a reputable shop to have them take a look at it to determine the cause.
